Even though the interracial relationships weren't the problem they were in the '50s, people still have issues with people dating outside of their race. In season three episode 23, "Mixed Blessings," Dorothy's son Michael makes an impromptu visit with big news — he's getting married. While Dorothy is still trying to digest the news, Michael adds that his new fiancée is black. Dorothy quickly processes but when she meets Lorraine, the fiancée, the 20-year age gap between the two takes precedent over her race. But, when Lorraine's family arrives, their concerns switch from the age gap to the fact that Michael is a "skinny white boy." The episode didn't get too deep into racism but considering its air date, we'll give it points for honourable mention.
